METHODS AND APPARATUS TO UPDATE MRB CONFIGURATION BY COMMON MULTICAST SIGNALING FOR MBS MULTICAST RECEPTION IN RRC INACTIVE STATE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240023142 titled 'METHODS AND APPARATUS TO UPDATE MRB CONFIGURATION BY COMMON MULTICAST SIGNALING FOR MBS MULTICAST RECEPTION IN RRC INACTIVE STATE
Simplified Explanation
The patent application describes an apparatus and methods for a User Equipment (UE) to receive multicast services while in the Radio Resource Control (RRC) inactive state. The UE joins a multicast session and receives an initial multicast configuration from a serving cell. It then monitors a common multicast signaling for the multicast session while in the RRC inactive state and updates the multicast configuration based on the common multicast signaling when predefined triggering conditions are detected. The UE can update the multicast configuration without notifying the network.
- The UE joins a multicast session and receives an initial multicast configuration from a serving cell.
- The UE monitors a common multicast signaling for the multicast session while in the RRC inactive state.
- The UE updates the multicast configuration based on the common multicast signaling when predefined triggering conditions are detected.
- The UE can update the multicast configuration without notifying the network.
- The UE can determine to perform a handover to a target cell if the source channel quality is below a predefined threshold.
- The UE performs handover to the target cell after reconfiguring the multicast to the target cell.
- The initial multicast configuration can be received in an RRC reconfiguration message or an RRC release message.
Potential applications of this technology:
- Efficient delivery of multicast services to User Equipment in the RRC inactive state.
- Improved management of multicast sessions for mobile devices.
- Enhanced user experience for receiving multicast services while conserving power.
Problems solved by this technology:
- Facilitates the reception of multicast services by User Equipment in the RRC inactive state.
- Enables seamless handover to a target cell while maintaining the multicast session.
Benefits of this technology:
- Allows User Equipment to efficiently receive multicast services without the need for constant network notifications.
- Enhances the overall user experience by providing uninterrupted multicast services during handover.
- Optimizes power consumption by efficiently managing multicast sessions in the RRC inactive state.
Original Abstract Submitted
apparatus and methods are provided for ue to receive multicast services in rrc inactive state. in one novel aspect, the ue joins a multicast session, receives an initial multicast configuration from a serving cell for the multicast, monitors a common multicast signaling for the multicast session in the rrc inactive state and updates the multicast configuration based on the common multicast signaling upon detecting one or more predefined triggering conditions. in one embodiment, the ue updates the multicast configuration without notifying network. in another embodiment, the ue determines to perform a handover to a target cell upon detecting the source channel quality is below a predefined threshold. in one embodiment, the ue performs handover to the target cell after reconfiguring the multicast to the target cell. in one embodiment, the initial multicast configuration is received in an rrc reconfiguration message or an rrc release message.
